This invention relates to improvements in devices for depositingexplosives in Well holes.

One object of the invention is to produce a 5 device of this nature thatis comparatively inexpensive but which will be reliable in its use,especially where the explosive such as dynamite, is loaded .in wellholes whose walls have irregularities therein. This safety feal0 ture isof importance because where cartridges are loaded in well holes havingirregular walls they are very apt to catch on the irregularities on thewall and must be either removed by tamping sticks, or rammed down 5until they pass below the irregularities.

\Vith these and other objects in view the invention consists in certaindetails of conof parts all as will hereinafter be more fully 50described and the novel features thereof particularly pointed out in theappended claims.

In the accompanying drawings Figure 1 is an elevational view of thepresent device before the cartridge is plaeed 55 therein, and

Fig. 2 is a similar view taken at rightangles to Fig. 1, but partiallybroken away to illustrate the cartridge loaded in the devlce. I Inaccordance with the present invention the device consists essentially ofa container that is preferably made of canvas, the diameter and lengthof the container being, of course, dependent upon the diameter of thewell hole into which the explosive is to be loaded and the length of thecartridge containing the explosive. Preferably, the ends of thecontainer, indicated at 10, has its ends reinforced by a multiplicity ofrows of stitching, indicated at 11.

' The casing is adapted to be lowered into the well hole by a cable orrope 12 which is attached to loops 13, 13*, stitched or otherwisesecurely attached to the exterior surface of the container 10 atopposite sides thereof.

The end of the container to which the cable is attached is, of course,the upper end of the container and the lower end of the container isprovided with means for removably supporting within the same thecartridge 16. In

accordance with the present invention these cartridge supporting meansconsist of two supporting elements 14, 14 attached to opposite sides ofcasing 10 and adapted to be detachably securedto each other byconnecting means indicated at 15. Preferably, these separable supportingelements 14, 14 are in the form of loops of any suitable fabric, and theconnecting means 15 should be readily breakable when subjected to suddenshock or strain. For instance, the medial portion of the loops 14, 14may simply be secured together by a piece of string. When so securedtogether they will support within the container the cartridge 16,asshown in Fig. 2.

When loading or lowering the cartridge into the well hole it is'placedin the container 10, as shown in Fig.2, and the container and cartridgelowered into the well. The strength of the string or other frangibleelement 15 is such as to normally support the weight of the cartridgebut when the container has been lowered to the point where it is desiredto deposit the cartridge a sudden jerk on the cable or rope 12 willcause the string 15., or a other fastening element, to break whereuponthe container may be slipped or drawn upwardly from around the depositedcartridge. It will be understood that where more than one cartridge isto be loaded into the well hole the operation just described will berepeated as'many times as is necessary to load the desired, number ofcartridges in the well.

Due to the low cost of loops of fabric such as shown, supportingelements of this nature are preferable, but it will be appreciated thatthe use of a frangible element for detachably connecting cartridgesupporting members is not necessarilylimited to the particular type 9 ofsupportingmember shown. I

What I claim is: 1. In a device of the character described, thecombination of an elongated tubular container open at one end, separatesupporting n elements at the open end of the container, and

means detachably connecting said elements to normally hold them inposition to span said open end and support a body in said container.

2. In a device of the character described,

the combination of an elongated tubular container adapted to besuspended in a well hole, said container being open at one end, separatesupporting elements at the open end of the container, and a readilybreakable member detachably connecting said supporting elements, saidsupporting elements when connected together being held in position tospan said open end and support a body in said container.

3. In a device of the character described, the combination of anelongated tubular container open at one end and adapted to be suspendedin a well hole, a plurality of loops attached to the open end of saidcontainer, and means for detachably connecting said loops together. saidloops when connected together being adapted to conjointly span said openend and form a support for a body within the container. I

4. In a device of the character described, the combination of anelongated tubular container open at one end and adapted to be suspendedin a well hole, a plurality of loops of binding material attached to theopen end of said container and a frangible connection between saidloops, said loops when connected being adapted to conjointly span saidopen end and form a support for a body Within the container.
